System and method for configuring a logging module

ABSTRACT

A method for configuring a logging module for logging sensors deployment based on a sensing data acquisition objective includes selecting a tool body, selecting at least one type of sensor, and selecting at least one type of roller. The method also includes incorporating the at least one selected type of sensor onto the at least one selected type of roller to provide at least one sensor roller, and mounting the at least one sensor roller into a compressible mounting assembly provided in the tool body to provide the logging module.

BACKGROUND

Traditionally, wireline logging sensors and logging while drilling (LWD)logging sensors need direct contact with a formation to measure andcollect various properties in a borehole. One common deployment oflogging sensors is to mount the logging sensors on a tool body that isdecentered using accessories such as bow spring or offset subs, so thatthe sensors contact with the formation under gravity. Another commondeployment is to mount the logging sensors on pad devices or flappersthat are deployed and extended mechanically away from the tool bodyusing electric or hydraulic motors. However due to the rough and complexenvironment in the borehole, these traditional logging sensorsdeployments face challenges such as poor contact with the formation,poor data resolution, and high maintenance due to damage to the sensors.

DETAILED DESCRIPTION

Specific embodiments of the disclosure will now be described in detailwith reference to the accompanying figures. Like elements in the variousfigures are denoted by like reference numerals for consistency.

In the following detailed description of embodiments of the disclosure,numerous specific details are set forth in order to provide a morethorough understanding of the disclosure. However, it will be apparentto one of ordinary skill in the art that the disclosure may be practicedwithout these specific details. In other instances, well-known featureshave not been described in detail to avoid unnecessarily complicatingthe description.

Throughout the application, ordinal numbers (e.g., first, second, third,etc.) may be used as an adjective for an element. The use of ordinalnumbers is not to imply or create any particular ordering of theelements nor to limit any element to being only a single element unlessexpressly disclosed, such as using the terms “before,” “after,”“single,” and other such terminology. Rather, the use of ordinal numbersis to distinguish between the elements. By way of an example, a firstelement is distinct from a second element, and the first element mayencompass more than one element and succeed (or precede) the secondelement in an ordering of elements.

In general, embodiments of the disclosure include a logging modulesystem and a method for configuring a logging module. In someembodiments, methods may include adopting various roller deploymentmodules and various types of sensors. For example, the various rollerdeployment modules may include an in-body roller module, wherein atleast one roller is fixed inside a logging module body and extends fromthe logging module body, and at least one sensor is mounted on eachroller. For another example, the various roller deployment modules mayinclude an over-body roller module, wherein at least one roller is fixedon an outer surface of a logging module body and extends from thelogging module body, and at least one sensor is mounted on each roller.Consequently, a new concept of logging sensors deployment on rollers isintroduced.

Further, some embodiments of the disclosure provide a method forgenerating an optimized logging module design. More specifically, theoptimized logging module design may be realized by a neural network. Forexample, various existing logging module design parameters and sensingdata retrieved from existing logging operations may be collected andentered into the neural network. Correlations between the logging moduledesign parameters and retrieved sensing data may be determined. As such,the optimized logging module designs may be generated by the neuralnetwork based on the known correlations.

Turning to FIG. 1 , FIG. 1 shows an example of a traditional loggingsensor deployment. As shown in FIG. 1 , logging sensors (e.g., loggingsensors 12) are mounted on pad devices (e.g., pad devices 11) that areattached to a tool body (e.g., tool body 10). Alternatively, the paddevices (11) may extend mechanically away from the tool body (10) (notshown). This traditional logging sensor deployment on pad devices faceschallenges and disadvantages. For example, due to the rough conditionand environment in the borehole, pad devices may suffer from corrosion,damage, or being lost, etc., and may have poor contact of the loggingsensors to the borehole, which results in poor resolution. Moreover, insome cases, logging sensor deployment on pad devices requires complexconveyance system and higher maintenance. In order to solve these issuescaused by the pad devices deployment, the disclosure provides a newconcept of logging sensors deployed on rollers that will be furtherdescribed below.

According to embodiments of the present disclosure, sensor rollers maybe mounted along a tool body and configured in a manner to allow thesensor rollers to roll along a well wall (e.g., a borehole or a casedwall). As used herein, a sensor roller (may also be referred to as a“Sens&Roll”) may refer to a roller having one or more sensors attachedaround an outer surface of the roller. As described more herein, rollersmay be selected from different shapes and sizes that are capable ofrotating with respect to an axis, and sensors may be selected fromdifferent types of sensors (e.g., depending on the type of data to becollected from the logging operation).

Turning to FIG. 2 , FIG. 2 provides an example of a logging modulehaving sensor rollers deployed in an in-body sensor roller deploymentconfiguration on a tool body in a borehole environment in accordancewith one or more embodiments. The following example is for explanatorypurposes only and not intended to limit the scope of the disclosedtechnology. As shown in FIG. 2 , a plurality of rollers (e.g., roller21) may be fixed inside a tool body (e.g., tool body 20) and extend fromthe tool body (20). A plurality of sensors (e.g., sensor 22) may bemounted on each of the plurality of rollers (21) to form sensor rollers(25). In addition, each of the sensor rollers (21) may be coupled with apair of wear fins (e.g., wear fins 23) fixed on the tool body (20). Thewear fins (23) may protrude a height (27) from the outer surface of thetool body, wherein the height (27) is less than a maximum extendingdistance (26) of the rollers (21), as measured perpendicularly from theouter surface of the tool body (20). The wear fins (23) may protect therollers (21) and the sensors (22) from wear and damages as the tool body(20) passes through sharp edges of a borehole surface (e.g., boreholesurface 24).

FIGS. 3A and 3B provide another example of an in-body sensor rollerdeployment module in accordance with one or more embodiments. As shownin FIGS. 3A and 3B, one roller (31) coupled with a pair of wear fins(33) may be fixed in a tool body (30) and partially extend from the toolbody (20). At least one sensor (32) (e.g., one, two, three, or moresensors) may be mounted on the roller (31).

However, in-body sensor roller deployment is not limited to what isshown in FIGS. 2-3B. For example, as shown in FIGS. 4A and 4B, tworollers (41) each coupled with a pair of wear fins (43) may be fixed inthe tool body (40) and partially extend from the tool body (40). Thenumber of in-body sensor rollers that may be deployed on a logging toolbody is not limited by the examples shown in FIGS. 2-4B, and may beselected, for example, based on logging operation parameters.

Further, as shown in FIGS. 2-4B, the plurality of rollers (21, 31, 41)may extend from the tool body (20, 30, 40) perpendicularly to the toolbody (20, 30, 40) surface and along a longitudinal axis Y of the toolbody (20, 30, 40). In other embodiments, sensor rollers may be in anon-planar alignment with the longitudinal axis of the tool body. Forexample, FIG. 5 shows another example of an in-body sensor rollerdeployment module in accordance with one or more embodiments. As shownin FIG. 5 , the plurality of rollers (51) may extend perpendicularlyfrom the tool body (50) surface, and tilt at an angle (angle α in FIG. 5) from the longitudinal axis Y of the tool body (50). The angle α may bemeasured between a longitudinal axis X of the roller (51) and thelongitudinal axis Y of the tool body (50) and may range from greaterthan 0° to 90°. In embodiments such as shown in FIG. 5 , where thesensor roller tilts to form an angle between a longitudinal axis X ofthe roller and the longitudinal axis Y of the tool body, the sensorroller may rotate while the tool body swivels in a corkscrew motion.When logging modules are moved through a conduit in a corkscrew motion(e.g., such as when a drill string is rotated as it is moved axiallythrough a well), a tilted sensor roller configuration may provide ahigher vertical resolution compared to a configuration where the sensorroller does not tilt. Further, as the angle α increases (between 0° to90°), the resolution may improve, but friction and operation complexitymay also increase.

FIGS. 6A and 6B provide another example of an in-body sensor rollerdeployment module in accordance with one or more embodiments.Specifically, as shown in FIGS. 6A and 6B, two individual in-body sensorrollers are combined to provide an in-line tandem deployment with anoffset angle (the angle β in FIG. 6B) of 90°. In some embodiments, thein-line tandem deployment may include more than two in-body sensorrollers, and the offset angle β may be larger than or equal to 0° andless than or equal to 180°. Further, the in-line tandem deployment isnot limited by what is shown in FIGS. 6A and 6B. For example, eachindividual in-body sensor roller of the in-line tandem deployment mayinclude a plurality of rollers deployed as shown in, but not limited to,FIGS. 2-5 , and each of the plurality of rollers may include a pluralityof sensors.

FIGS. 7A-7D show different designs of a roller (21, 31, 41, 51). Forexample, the roller (21, 31, 41, 51) may be a cylinder shape as shown inFIGS. 7A and 7B. The roller (21, 31, 41, 51) may be a frustum of a coneshape as shown in FIGS. 7A and 7C. In some embodiments, the roller (21,31, 41, 51) may be a wheel shape having a sidewall with a convexprofile, as shown in FIGS. 7A and 7D. However, the roller shape is notlimited to these shapes.

Turning to FIG. 8 , FIG. 8 provides an example of a logging modulehaving sensor rollers attached to a tool body in an over-body deploymentconfiguration in accordance with one or more embodiments. The followingexample is for explanatory purposes only and not intended to limit thescope of the disclosed technology. As shown in FIG. 8 , a plurality ofrollers (e.g. roller 81) may be mounted on the external surface of atool body (e.g., tool body 80). Further, a plurality of sensors (e.g.,sensor 82) may be mounted on each of the plurality of rollers (81) toform the sensor rollers (85). Similar to the in-body sensor rollersdeployment, each of the plurality of rollers (81) of the over-bodysensor rollers deployment may be coupled with a pair of wear fins (e.g.,wear fins 83) fixed on the tool body (80). The wear fins (83) may aid inprotecting the sensor rollers (85) as the logging module travels througha borehole (84).

FIGS. 9A-9C provide another example of over-body sensor rollers inaccordance with one or more embodiments. As shown in FIGS. 9A and 9B,one roller (91) coupled with a pair of wear fins (93) may be fixed onthe outer surface of a tool body (90). At least one sensor (92) may bemounted on the roller (91). In some embodiments, as shown in FIG. 9C,the roller (91) may be mounted via a journal (e.g., journal 96) that isconnected to the tool body (90). The journal (96) has the ability toaxially move via a spring (97) to improve the flexibility of the roller(91), so that the roller may extend over the surface of the tool body(90) and/or move towards the tool body along the axis (96).

FIG. 9D shows an alternative mounting configuration for a sensor rollerrotatably mounted to a tool body (90) in an over-body deploymentconfiguration. The tool body (90) may be, for example, a wall of atubular (e.g., a drill string or BHA). As shown, the sensor rollerincludes a sensor (92) attached to a roller (91). The roller (91) has ahemispherical protruding portion shape and a journal (96) extendingtoward the tool body (90) from the protruding portion of the roller(91). The journal (96) may be co-axial with a central axis (94) of theroller (91). The journal (96) may be rotatably mounted to a compressiblemounting assembly (99) on the tool body (90), such that the roller (91)may rotate (95) about its central axis (94).

The mounting assembly (99) may include, for example, a spring (97) orother type of force mechanism to provide the roller (91) with a limitedamount of axial movement (98). In such manner, the sensor roller may beaxially compressible/expandable (98) in a direction parallel with thecentral axis (94) of the roller (91). The mounting assembly (99) mayfurther be oriented at an angle from a line perpendicular with the outersurface of the tool body (90). Thus, when the roller (91) is mounted tothe mounting assembly (99), the roller (91) may also be oriented at anangle offset from a perpendicular orientation to the outer surface ofthe tool body (90). Once mounted, the sensor roller may be rotatable(95) about its central axis (94) and axially compressible/expandable(98) along a direction parallel with the central axis (94). Further,wear fins (93) may be mounted to the outer surface of the tool body (90)around the sensor roller.

However, over-body sensor roller deployment is not limited to what isshown in FIGS. 8-9D. For example, as shown in FIGS. 10A and 10B, foursensor rollers (101) each having at least one sensor (102) and coupledwith a pair of wear fins (103) may be fixed on the outer surface of atool body (100). The number of sensor rollers in an over-body deploymentis not limited by the examples shown in FIGS. 8-10B.

FIGS. 11-14 show section views of various designs of sensor rollers(1101, 1201, 1301, and 1401) on a tool body (1100, 1200, 1300, and 1400)in an over-body deployment configuration. However, the roller shape ofthe over-body sensor rollers is not limited to these shapes. Forexample, the roller shape may be flat, spherical, elliptical, conical,hemispherical, polyhedral, and etc., and the edge of the roller shapemay be curved or sharped.

According to embodiments of the present disclosure, sensor rollers mayhave various shapes capable of rotating about an axis (for example,including a journal (96) in FIG. 9C). One or more sensors may be mountedon an outer surface of the roller, along a portion of the outer surfacethat may be contacted against a well wall when the sensor roller isrolled along the well wall.

For example, referring again to FIGS. 2 and 8 , the rollers (21, 81) maycontact and roll along an external surface (e.g., external surface 24and 84), such as surface of a casing, a tubing, formation wall, orborehole wall, etc. In order to achieve flexible adherence, the rollers(21, 81) may be partially extendable slightly over the wear fins (23,83) in a direction that is perpendicular to the tool body (20, 80). Morespecifically, the rollers (21, 81) may be mounted in a compressiblemounting assembly and extend from the tool body (20, 80) under a passivesystem or active system in the compressible mounting assembly. A passivesystem, such as springs positioned within the tool body (20, 80), may beconnected to each of the rollers (21, 81) and provide compressive forceto each of the rollers. In some embodiments, one roller may be connectedto one or more springs, either directly or through a journal. An activesystem, such as an electrical motor or a hydraulic motor, may providecontrollable force to each of the rollers (21, 81).

For example, FIG. 15 shows a cross sectional view of a logging modulehaving a plurality of sensor rollers (1501) in different radiallycompressed configurations as the logging module travels through apipeline casing (e.g., pipeline casing (1505). As shown in FIG. 15 ,pipeline casing (e.g., pipeline casing 1505) may have corrosion andscale. When the logging module having the in-body sensor rollers (1501)is used for pipeline inspection, the sensor rollers (1501) may moveslightly over the wear fins (e.g., wear fins 1503) to contact thecorrosion of the pipeline casing (1505), and may move slightly towardsthe center of a tool body (e.g., tool body 1500) due to the pressurefrom scale of the pipeline casing (1505). Sensors (1502) may be providedalong the outer surface of the rollers such that it may contact thepipeline casing (1505) as the logging module moves through the pipeline.

Further, keeping with FIGS. 2 and 8 , in one or more embodiments, thetool body (20, 80) may refer to a part of a logging tool, which is aconveyance that carries the logging module. For example, the tool body(20, 80) may be a bottom hole assembly (BHA). A BHA may include a drillbit and one or more drill bit accessories, such as drill collar(s),stabilizer(s), a downhole motor, etc. and may be attached at the lowestpart of a drill string. A drill string may include connected togetherdrill pipes, drill collars, and drill bit (or BHA). A BHA may havevarious components and equipment that are designed to provide enoughweight for the drill bit, and to direct the drill bit to a specificdepth or move along a planned trajectory. Moreover, the tool body (20,80) may be wireline, logging while drilling (LWD) tool, coil tubing,slickline, fiber line, etc.

In addition, in some embodiments, the logging modules may be utilizedwithout a tool body. For example, for pipeline inspection, the loggingmodule may be delivered to a target position in the pipeline viaconveyance such as fluid flow. For another example, for downholeapplications, the module may be delivered to a desired depth viamotorized robot or weight ball dropping techniques. Sensors or part ofthe sensors may be positioned to always contact the external surface(24, 84), such as a casing/tubing inner wall and borehole wall, eitherdirectly, or indirectly. For example, as shown in FIGS. 16A and 16B, asensor (e.g., sensor 1602) may contact an inner surface of a casing(e.g., casing 1605) through a magnet strip (e.g., magnet strip 1607).FIG. 16A shows an axial cross sectional view of the roller sensorcontacting the inner surface of the casing (1605). FIG. 16B shows across sectional view along the axial length of the casing (1605) and aside view of the roller sensor, where the roller sensor includesmultiple sensors (1602) disposed on an outer surface of a roller (1601)and a magnet strip (1607) wrapped around the outer surface of theroller.

While FIGS. 2-16 show various configurations of components, otherconfigurations may be used without departing from the scope of thedisclosure. For example, various components in FIGS. 2-16 may becombined to create a single component. As another example, functionalityperformed by a single component may be performed by two or morecomponents.

In some embodiments, a plurality of sensor rollers can be directlysupported by the tool body. Alternatively, a plurality of sensor rollerscan be mounted on a sleeve or a pair of brackets, for example, the wearfins. Through the sleeve or the brackets, the plurality of sensorrollers may be mounted either tethered or untethered. A tetheredconfiguration may refer to configurations where the plurality of sensorrollers are mechanically supported by the sleeve or the brackets, butare electrically connected to the tool body for communication and powerpurposes. An untethered configuration may refer to configurations thatwhile the plurality of sensor rollers are mechanically supported on thesleeve or the brackets, the plurality of sensor rollers performfunctions autonomously and communicate with the tool body throughwireless communication. In the latter case, the tool body may provideconvenient conveyance for the plurality of sensor rollers by reducingfriction in the downhole, surface tubing, case casing, or borehole.

Moreover, in some embodiments, sensor rollers may be configured to beremovable from the tool body. Further, in some embodiments, sensorrollers may be configured so that each of them is able to rotatecontinuously about its central axis. For example, the arrows in FIGS. 3Aand 9C show possible rotation directions of the sensor rollers.Therefore, each sensor on the plurality of rollers may directly andequally contact the formation to achieve maximum coverage and contact onthe formation surface. Further, in some embodiments, sensor rollers maybe configured so that they have the ability to move slightly indirections perpendicular to the tool body and/or in directions that formacute angles with the outer surface of the tool body.

In some embodiments, one or more sensors may be mounted on the surfaceof one or more rollers. Alternatively, one or more sensors may bemounted inside one or more rollers. As such, the sensors may contact theexternal surface either directly or from a specific distance (fromwithin a roller). Sensors may be miniaturized sensors that fit in astandard borehole size. For example, sensors may have a cylinder shapehaving a diameter between 3-5 inches and thickness of 1 inch.Furthermore, to achieve different objectives, sensors may be varioustypes of sensors using different physics, including nuclear (e.g.,gamma-ray sensor and Nuclear Magnetic Resonance (NMR) sensor),electrical sensors (e.g., resistivity sensor, dielectric sensor, andpiezoelectric sensor), sonic sensors (e.g., ultrasonic sensor andseismic sensor), chemical sensors, electrochemical sensors, opticalsensors, temperature sensors, pressure sensors, and etc.

In some embodiments, different numbers and types of sensors may be usedstrategically in various sensor rollers to achieve various logging andsensing objects. In some embodiments, same type of sensors withdifferent measurement modes or sensing ranges may be deployed on thesame roller. Further, one roller with more sensors may provide higherresolution, including vertical resolution and azimuthal resolution. Forexample, a roller having two sensors positioned around its circumferencemay provide double resolution (as the tool moves) compared to the sameroller with one sensor only.

Embodiments of the disclosure may include a method of designing and/orconfiguring a logging module. For example, in some embodiments, a toolbody, one or more rollers of various roller designs, and/or one or moretypes of sensors may be selected in order to configure the loggingmodule in accordance with a pre-determined sensing data acquisitionobjective (e.g., to perform formation evaluation and to acquire aborehole profile, etc., in an open hole environment; and to performcement evaluation, casing(s) inspection, production logging, wellintervention, etc., in a cased hole environment). Further, the selectedone or more sensors may be incorporated on the selected one or morerollers to form sensor rollers, and the one or more sensor rollers maybe mounted onto the selected tool body to configure the logging module.In some embodiments, the tool body of the logging module may be selectedbased on an inner diameter of the well to be logged. For example, for awell or borehole with small inner diameter, a wire line that takes lessspace may be a better option compared with using a BHA tool as the toolbody.

In addition, in some embodiments, a first configured logging moduleincluding a first set of sensor rollers may be used in a first loggingoperation. Afterwards, at least one of the first sensor rollers may beremoved, and one or more second sensor rollers that are different fromthe removed first sensor rollers may be mounted in the mounting assemblythat previously held the removed first sensor rollers. The second sensorrollers may have at least one sensor roller design parameter (e.g.,roller design parameters such as size, material, and/or shape of roller,and/or sensor design parameters such as amount of sensors,wired/wireless communication design, and/or type of sensor) that isdifferent from the first set of rollers and sensors. In such manner, asecond logging module with a second set of sensor rollers may beconfigured and used for a second logging operation different than thefirst logging operation.

Keeping with the above description, the sensor roller design parametermay refer to various designs regarding the rollers and sensors, andlogging module design parameters may refer to sensor roller designparameters as well as the design of additional logging module features.For example, logging module design parameters may include the number ofrollers and sensors, roller shape, rollers and sensors deploymentpositions on the tool body, tool body type (e.g., tool body shape andsize), and sensor data communication protocol (e.g., through one or morewireless transmitters or through a wire), etc. The sensor roller designparameters may also include, but not limited to, the design parametersshown in FIGS. 2-16 and described in the accompanying description.

While the various steps of the above method of configuring the loggingmodule are described sequentially, one of ordinary skill in the art willappreciate that some or all of the steps may be executed in differentorders, may be combined or omitted, and some or all of the steps may beexecuted in parallel. Furthermore, the steps may be performed activelyor passively.

Embodiments of the disclosure may include a method of generating anoptimized logging module design. The optimized logging module design maybe realized using a neural network that includes a model. The neuralnetwork and the model will be further described below in FIG. 17 and theaccompanying description.

Turning to FIG. 17 , FIG. 17 provides an example of generating a modelto use for generating an optimized logging module design. The followingexample is for explanatory purposes only and not intended to limit thescope of the disclosed technology. In FIG. 17 , a model (e.g., model1705) is trained for generating an optimized logging module design(e.g., optimized logging module design 1730). The model (1705) mayobtain two inputs for training, i.e., logging module design parameters(e.g., logging module design parameters 1710) associated with anexisting logging module, and retrieved sensing data (e.g., retrievedsensing data 1720) from a plurality of logging operations using theexisting logging module. The retrieved sensing data (1720) may includevarious well parameters of a well (e.g., size of the borehole, ifdrilling fluid is present, etc.) for the plurality of loggingoperations.

As shown in FIG. 17 , the output of the model (1705) may include theoptimized logging module design (1730). Specifically, the model (1705)may be trained to compare the retrieved sensing data (1720) with aplurality of known well parameters of the well to determine a comparisonresult. The model (1705) may also be trained to adjust the loggingmodule design parameters (1710) to generate the optimized logging moduledesign (1730) based on the comparison result. Moreover, the optimizedlogging module design (1730) may be used for various of new loggingoperations to retrieve new sensing data. The optimized logging moduledesign (1730) and the newly retrieved sensing data may be collected andinputted into the model (1705) in order to update the optimized loggingmodule design (1730). For example, the optimized logging module designmay include at least one of the sensor roller design parameters, asdescribed above, a module conveyance parameter (including the type oftool body (e.g., a BHA) and/or conveyance method e.g., wireline, drillstring, coiled tubing), and a data telemetry parameter (communicationmethod between the sensors and data receivers, e.g., wired communicationor wireless communication).

Embodiments disclosed herein may be implemented on a computing system.Any combination of mobile, desktop, server, router, switch, embeddeddevice, or other types of hardware may be used. For example, as shown inFIG. 18 , the computing system (1800) may include one or more computerprocessors (1802), non-persistent storage (1804) (e.g., volatile memory,such as random access memory (RAM), cache memory), persistent storage(1806) (e.g., a hard disk, an optical drive such as a compact disk (CD)drive or digital versatile disk (DVD) drive, a flash memory, etc.), acommunication interface (1812) (e.g., Bluetooth interface, infraredinterface, network interface, optical interface, etc.), and numerousother elements and functionalities.

The computer processor(s) (1802) may be an integrated circuit forprocessing instructions. For example, the computer processor(s) may beone or more cores or micro-cores of a processor. The computing system(1800) may also include one or more input devices (1810), such as atouchscreen, keyboard, mouse, microphone, touchpad, electronic pen, orany other type of input device. In some embodiments, the computerprocessor(s) (1802) may have function to execute instructions toconfigure the optimized logging module design as described above in FIG.17 and the accompanying description.

The communication interface (1812) may include an integrated circuit forconnecting the computing system (1800) to a network (not shown) (e.g., alocal area network (LAN), a wide area network (WAN) such as theInternet, mobile network, or any other type of network) and/or toanother device, such as another computing device. In some embodiments,the communication interface (1812) may have the function to realizecommunication with the sensors, either via a wire or wirelessly.

Further, the computing system (1800) may include one or more outputdevices (1808), such as a screen (e.g., a liquid crystal display (LCD),a plasma display, touchscreen, cathode ray tube (CRT) monitor,projector, or other display device), a printer, external storage, or anyother output device. One or more of the output devices may be the sameor different from the input device(s). The input and output device(s)may be locally or remotely connected to the computer processor(s)(1802), non-persistent storage (1804), and persistent storage (1806).Many different types of computing systems exist, and the aforementionedinput and output device(s) may take other forms.

Software instructions in the form of computer readable program code toperform embodiments of the disclosure may be stored, in whole or inpart, temporarily or permanently, on a non-transitory computer readablemedium such as a CD, DVD, storage device, a diskette, a tape, flashmemory, physical memory, or any other computer readable storage medium.Specifically, the software instructions may correspond to computerreadable program code that, when executed by a processor(s), isconfigured to perform one or more embodiments of the disclosure. In someembodiments, the software instructions may include instructions toperform generation of the optimized logging module design as describedin FIG. 17 and the accompanying description.

The extracted data may be used for further processing by the computingsystem. For example, the computing system of FIG. 18 , while performingone or more embodiments of the disclosure, may perform data comparison.Data comparison may be used to compare two or more data values (e.g., A,B). For example, one or more embodiments may determine whether A>B, A=B,A !=B, A<B, etc. The comparison may be performed by submitting A, B, andan opcode specifying an operation related to the comparison into anarithmetic logic unit (ALU) (i.e., circuitry that performs arithmeticand/or bitwise logical operations on the two data values). The ALUoutputs the numerical result of the operation and/or one or more statusflags related to the numerical result. For example, the status flags mayindicate whether the numerical result is a positive number, a negativenumber, zero, etc. By selecting the proper opcode and then reading thenumerical results and/or status flags, the comparison may be executed.For example, in order to determine if A>B, B may be subtracted from A(i.e., A−B), and the status flags may be read to determine if the resultis positive (i.e., if A>B, then A−B>0). In one or more embodiments, Bmay be considered a threshold, and A is deemed to satisfy the thresholdif A=B or if A>B, as determined using the ALU. In one or moreembodiments of the disclosure, A and B may be vectors, and comparing Awith B includes comparing the first element of vector A with the firstelement of vector B, the second element of vector A with the secondelement of vector B, etc. In one or more embodiments, if A and B arestrings, the binary values of the strings may be compared.

The computing system in FIG. 18 may implement and/or be connected to adata repository. For example, one type of data repository is a database.A database is a collection of information configured for ease of dataretrieval, modification, re-organization, and deletion. A DatabaseManagement System (DBMS) is a software application that provides aninterface for users to define, create, query, update, or administerdatabases. In one or more embodiments, the data repository may be usedto store retrieved sensing data, logging module design parameters, andwell parameters, e.g., as described in FIG. 17 and the accompanyingdescription.

The user, or software application, may submit a statement or query intothe DBMS. Then the DBMS interprets the statement. The statement may be aselect statement to request information, update statement, createstatement, delete statement, etc. Moreover, the statement may includeparameters that specify data, or data container (database, table,record, column, view, etc.), identifier(s), conditions (comparisonoperators), functions (e.g. join, full join, count, average, etc.), sort(e.g. ascending, descending), or others. The DBMS may execute thestatement. For example, the DBMS may access a memory buffer, a referenceor index a file for read, write, deletion, or any combination thereof,for responding to the statement. The DBMS may load the data frompersistent or non-persistent storage and perform computations to respondto the query. The DBMS may return the result(s) to the user or softwareapplication.

The computing system of FIG. 18 may include functionality to present rawand/or processed data, such as results of comparisons and otherprocessing. For example, presenting data may be accomplished throughvarious presenting methods. Specifically, data may be presented througha user interface provided by a computing device. The user interface mayinclude a GUI that displays information on a display device, such as acomputer monitor or a touchscreen on a handheld computer device. The GUImay include various GUI widgets that organize what data is shown as wellas how data is presented to a user. Furthermore, the GUI may presentdata directly to the user, e.g., data presented as actual data valuesthrough text, or rendered by the computing device into a visualrepresentation of the data, such as through visualizing a data model. Insome embodiments, the functionality to present raw and/or processed datamay be performed while generating an optimized logging module design,e.g., as described in FIG. 17 and the accompanying description.

For example, a GUI may first obtain a notification from a softwareapplication requesting that a particular data object be presented withinthe GUI. Next, the GUI may determine a data object type associated withthe particular data object, e.g., by obtaining data from a dataattribute within the data object that identifies the data object type.Then, the GUI may determine any rules designated for displaying thatdata object type, e.g., rules specified by a software framework for adata object class or according to any local parameters defined by theGUI for presenting that data object type. Finally, the GUI may obtaindata values from the particular data object and render a visualrepresentation of the data values within a display device according tothe designated rules for that data object type.

Data may also be presented through various audio methods. In particular,data may be rendered into an audio format and presented as sound throughone or more speakers operably connected to a computing device.

Data may also be presented to a user through haptic methods. Forexample, haptic methods may include vibrations or other physical signalsgenerated by the computing system. For example, data may be presented toa user using a vibration generated by a handheld computer device with apredefined duration and intensity of the vibration to communicate thedata.

The above description of functions presents only a few examples offunctions performed by the computing system of FIG. 18 . Other functionsmay be performed using one or more embodiments of the disclosure.
